gold nanoparticles are commonly produced in a liquid by reducing chloroauric acid. after dissolving the acid, the solution is rapidly mixed along with a reducing agent. this process then cause au+3 ions to be reduced to neutral gold atoms. gold nanoparticles are small gold particles with a diameter of one to one hundred nm which, once dispersed in water are also, known as colloidal gold. it is a soft metal that is often alloyed to give it more strength. it is a good reflector of heat and electricity so it is a great reflector of infrared and is chemically inert. there are a few gold nanoparticles supplier around the world, also to provide these, we should go to centers of sale. gold nano particles have a different applications, for example: physical properties, thermal properties, chemical properties.
Best nanoparticle producers around the world
gold nanoparticles are versatile materials with a broad range of applications in a variety of fields. researchers have coated gold particles with DNA and injected them into plant embryos or plant cells. this will ensure that some genetic material will enter the cells and transform them. this method enhances plant plastids. there are many nanoparticles producers around the world, that produced different models and type of nanoparticles.

Important tips to pay attention while buying nanoparticles
gold nanorods applications are specific, the optical electronics properties of gold nanoparticle are being explored widely for use in high technology applications such as sensory probes, electronic conductors, therapeutic agents, organic photovoltaics, drug delivery in biological and medical applications and catalysis.
list of application of gold nanoparticles:
- as and anti biotic, anti fungal and anti microbial agent when added in plastic, coating, nano fibers and textiles
- in nano wires and catalyst applications
- in therapeutic agent delivery
- for fuel cell applications
- as catalysts in a number of chemical reactions
- to detect bio markers in the diagnosis of cancers. heart diseases, and infectious agents
- the scattered colors of gold nanoparticles are currently used for biological imaging applications
- gold nanoparticles are quite dense thus allowing them to be used as probes for transmission electron microscopy
Understanding the interaction of gold and silver nanoparticles
nanopartz gold nanoparticles are nanorod shaped gold nano particles manufactured using proprietary and patented methods that result in exact sizes, highly monodisperse sizes and shapes, long shelf lives, along with significantly improved reactivity. we describe the synthesis of charge stabilised gold and silver nanoparticles by a modified special method and their interaction with a selection of cationic and anionic dyes. it was found that gold nanoparticles interact strongly with cationic dyes and in some cases enhanced absorption was observed by UV visible spectroscopy. it is also shown that addition of cationic dyes to gold nanoparticles triggers micrometre scate clusters. simultaneous fragmentation and agglomeration of the gold nanoparticles was observed at high concentrations of cationic dye in the solution so this effect were not observed when gold nanoparticles were mixed with anionic dyes, nor for silver nanoparticles with either cationic or anionic dyes.
